The trading allowance lets you earn up to £1,000 from self-employment or casual work without paying tax on it. But you need to decide whether to use this allowance or claim your actual expenses instead - you cannot do both.

What is the trading allowance?

The trading allowance is a £1,000 tax-free allowance for individuals with trading or miscellaneous income. It was introduced in April 2017 to simplify tax for people with small amounts of self-employment income.

Who can claim it?

The trading allowance is available to individuals only. You can claim it on income from self-employment, casual work, or miscellaneous sources like hiring out personal equipment. However, there are important restrictions.

Allowance or expenses - how to decide

This is the key decision. You must choose one method only for each tax year - you cannot claim the allowance and also deduct actual expenses.

Use the trading allowance when:

  • Your actual business expenses are less than £1,000
  • You want to keep things simple with minimal record-keeping
  • Your gross income is £1,000 or less (you pay no tax either way)

Claim actual expenses when:

  • Your expenses exceed £1,000
  • You want to claim a trading loss (allowance cannot create a loss)
  • You have significant capital allowances to claim
  • Your business has substantial costs (stock, equipment, premises)

Example decision:

  • Sarah earns £3,000 from freelance writing with £400 in expenses. Using the allowance gives her £2,000 taxable profit. Claiming expenses gives her £2,600 taxable profit. The allowance wins.
  • Tom earns £3,000 from car boot sales with £1,500 in stock costs. Claiming expenses gives him £1,500 taxable profit. The allowance would give him £2,000 taxable. Expenses win.

Important restrictions

Before you decide to use the trading allowance, check these restrictions carefully.

Property allowance - a separate £1,000

If you have property income as well as trading income, there is good news. The property allowance is completely separate from the trading allowance.

Practical example

  • You earn £800 from occasional freelance work (trading income)
  • You earn £600 from renting out your parking space (property income)
  • Both are under £1,000, so you can use both allowances
  • Result - no tax to pay, no need to register for Self Assessment

When you do not need to register for Self Assessment

If your total trading income is £1,000 or less, you do not need to register for Self Assessment or tell HMRC about this income. The allowance automatically applies.

If you already file a Self Assessment return for other reasons (employment over £100,000, rental income, etc.), you can still use the trading allowance - just do not include the trading income if it is under £1,000, or elect partial relief if it exceeds £1,000.

National Insurance implications

If you use the trading allowance and your profits are reduced to nil, you will not owe Class 2 National Insurance. However, this could affect your state pension entitlement. You may want to pay voluntary Class 2 contributions (£3.50 per week in 2025/26) to protect your NI record.

Common mistakes to avoid

  • Claiming both - You cannot use the allowance and claim expenses in the same tax year
  • Ignoring restrictions - Any excluded income (from employer, spouse's employer, or connected partnership) disqualifies all your trading income from the allowance
  • Forgetting capital allowances - If you use the trading allowance, you cannot claim capital allowances that year
  • Multiple trades - The £1,000 allowance is shared across all your trades and miscellaneous income - not £1,000 per trade
  1. Calculate your gross trading income

    Add up all income from self-employment and miscellaneous sources before any expenses.

  2. Calculate your actual expenses

    Work out what you could deduct if claiming expenses - include allowable business costs and capital allowances.

  3. Compare the two methods

    If expenses are less than £1,000, the allowance is better. If expenses exceed £1,000, claim them instead.

  4. Check for excluded income

    If you receive any income from an employer, spouse's employer, or connected partnership, you cannot use the allowance at all.

  5. Decide on National Insurance

    If using the allowance reduces profits to nil, consider voluntary Class 2 NI to protect your state pension.

  6. Apply the right relief

    Under £1,000 = full relief (no return needed). Over £1,000 = elect partial relief when filing your return.

THRESHOLD £1,000

No registration required

turnover threshold: £1,000

If your total self-employment income is £1,000 or less, you do not need to register for Self Assessment or report this income to HMRC.

Above threshold:

You must register for Self Assessment. You can then choose to use the trading allowance (reducing taxable profit by £1,000) or claim actual expenses.

Below threshold:

The trading allowance automatically covers your income. You have no tax to pay and no filing requirements for this income.

Strategic considerations: Even below £1,000, you might want to register if you need to prove self-employment for mortgages, Universal Credit, or if you want to pay voluntary Class 2 NI for State Pension credits.
SOLE TRADER Advantage

Trading allowance simplifies small-scale self-employment

The trading allowance is designed for sole traders with small amounts of self-employment income. It offers:

  • No registration needed if income is under £1,000
  • Simplified record-keeping - no need to track every receipt
  • Flat deduction of £1,000 from income over £1,000

Comparison to other structures:

Limited companies cannot use the trading allowance. All company income and expenses must be properly recorded and reported through Corporation Tax returns.

When this matters: The allowance is ideal for casual freelancing, gig economy work, or testing a business idea before fully committing to self-employment.
